11. The high-efficiency pump is controlled by a PWM
signal which is provided by the solar controller.
The pump capacity is determined by the control
signal of the controller. This signal depends on
the temperature difference between the collector
and storage cylinder sensors. Hydronic regulation
can be carried out with the help of the adjustment
screw at the flow measuring device (see point 6.3).
12. Mount the front insulation (4) and insulate the
supply and return pipes up to the thermal
